标签：map iterator get jsonobject next filter key jsonObject
if (filter.containsKey("nodeData")) {
JSONObject jsonObject = (JSONObject) filter.get("nodeData");
Iterator iterator = jsonObject.keySet().iterator();
while (iterator.hasNext()){
String next = (String) iterator.next();
Object o = jsonObject.get(next);
filter.put(next,o);
}
}
filter是一个Map<String, Object>，
containsKey判断是否存在nodeDatakey
keySet获取jsonobject对象的key
jsonObject.get(next)获取对应value
